Former Cincinnati Bearcats standout Gary Clark's second NBA start went better than his first - from a scoring standpoint, at least.

Clark scored a career-high 14 points - on 5-of-9 shooting from the field and 3-of-7 from 3-point range - adding five rebounds, one assist and one blocked shot in 31 minutes of action in the Houston Rockets' 121-118 come-from-behind win against the Miami Heat on Thursday night.

Last month, Clark made his first-ever NBA start - at center, no less - and took three of the Rockets' 35 3-point field-goal attempts in the first half against the Brooklyn Nets - an NBA record for most 3-point tries in a half. Clark missed all five of his shot attempts in the game but grabbed eight rebounds and added two steals and two blocks in 23 minutes of action in Houston's 145-142 overtime loss.

Clark and former Middletown High School star Vincent Edwards of Purdue were part of a Houston roster of 14 entering the regular season. Edwards has played mostly with the G League's Rio Grande Valley Vipers - though he was active for the Rockets on Thursday night - while Clark has remained with the parent club thanks in large part to his impressive preseason.

Rockets head coach Mike D'Antoni said he was stunned that Clark wasn't drafted. In five preseason games, Clark averaged 7.6 points, 3.6 rebounds and 1.2 blocks in 16.6 minutes per game and shot 55.6 percent from 3-point range.
